DANIEL OGONNOR, OF LITTLE ROCK, ARKANSAS.

SWITCH STAND AND LOCK.

SPECIFICATION forming part of Letters Patent No. 265,132, datedSeptember 26,1882.

Application filed April 18, 1882. (No model.)

To all whom it may concern Be it known that I, DANIEL OComvoa, of LittleRock, in the county of Pulaski and State of Arkansas, have invented anewand useful Improvement in Switch Stands and Locks, of

which the following is a full, clear, and exact description.

My invention relates to devices for changing ,target, a sleeve, a latch,and a lever, whereby several advantages are obtained, as hereinaftermore particularly described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view of an apparatus einbodying my improvements. Fig.2 is a view at right angles to Fig. 1. Fig. 3 is a horizontal sectiontaken in the line war, Figs. 1 and 2. Fig. 4 is a vertical section of aportion of the lever and shaft and the sleeve and latch.

The switch-standis made of cast or wrought iron or steel, having abase-plate, B, top plate, 0, and lateral wings or fins D. The top plate,0, is provided with notches, as here shown. The plate has two notches,0, one at each side and in line with the wings D, and a third notch, c,at the front of the plate, in which front notch the lever-bar H isengaged. The vertical target shaft or standard F works in bearings inthe top plate, 0, and base-plate B, so that it may be turned therein. Tothe shaft F is attached a horizontal arm, G, to the outer end of whichis pivoted a bar, H, thus forming a hinged or jointed lever. This leverG H is above the plate 0, and when the bar H hangs down it engageswithone of the notches in the plate. Below the top plate, 0, a sleeve ortube, J, is attached to the shaft F, parallel with the arm G, by meansof a screw-threaded tang, t', screwed into said shaft. Inside of thissleeve or tube J is secured by welding the inner end of a springlatch,K, the outer end of which projects and engages with a recess, h, in thebar H, which recess also engages with the outer end of the sleeve ortube J, as shown in Fig. 4E. The recess h is provided with a keyhole, I,to admit of the insertion of a key to raise the latch K.

The operation is as follows: To reverse the target M, the latch K israised by meansofa key, the bar H is pulled out and raised clear of itsnotch e, and the shaft F is rotated by moving the bar H in one directionor the other. When the desired position is reached the bar H is dropped,so as to engage with Opposite notch, e, and allow thelatch K and sleeveor tube J to engage with the recess h, and the apparatus is then looked.The switch-stand being secured with wings D and side notches, e,

in line with the rails, when the bar H is engaged in the outer notch, e,as shown in Figs. 1, 2, and 3, the edge of the target M will bepresented to view from either direction along the track, and when bar His locked in either one of the side notches, c, the reverse anddifferently-colored sides of the target wiil be visible from eitherdirection along the rails, as may be desired. 1

The advantages of my invention are: It is cheap and simple inconstruction, easily operated, and not liable to get out oforder. It maybe allowed to remain locked or unlocked at pleasure, and when locked itcannot be unlocked without a key, and it may be arranged to hold thetarget-shalt at any desired number of positions.

The invention may be applied to a switch: stand already in use byattaching a collar to the target-shaft F and attaching the sleeve J andlatch K to said collar.

Havingthus fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The combination, with the base B, the notched top plate, 0, and thetarget shaft or standard F, of the arm G, the bar H, pivoted to saidarm, and means, substantially as shown and described, for locking saidbar to the target-shaft, as set forth.

2. The combination, with the sleeve or tube J and spring-latch K, of thebar H, provided with the recess h, as shown and described, for p DANIELOOONN OR.
